Flow chart when Fig. 1 is event information in host computer in the prior art or system reading power meters
Fig. 2 is flow chart of the present invention
Specific embodiment
As shown in Fig. 2, a kind of transmission method of electric energy meter event information, comprising the following steps:
S1, beginning；
S2, host computer or system and electric energy meter carry out communication protocol matching, when host computer or system are used with electric energy meter
Communications protocol it is identical when could successful match, if communication protocol successful match, enter in next step；If communications protocol matches not
Success then enters S7；
S3, host computer or system and electric energy meter establish communication connection, if communication connection success, enters in next step；If logical
Connection failure is interrogated, then enters S7；
S4, host computer send the order for reading event information collection to electric energy meter, if electric energy meter normally receives the reading event
The order of information collection then enters in next step, if electric energy meter cannot normally receive the order of the reading event information collection, enters
S7；
S5, electric energy meter read event information collection from memory and the event information collection are sent to host computer, event letter
Breath, which is concentrated, includes at least an event information, and each event information is preset with serial number, and the type of serial number and event information is one by one
It is corresponding；The storage format of event information collection are as follows: the event information+the second of mode bit+the first event information of event information+...
Nth event information, wherein N is positive integer；It include that first event information to nth event is believed in the mode bit of event information
The serial number of breath；The mode bit of event information with N number of event information thereafter for being mutually authenticated, for example, the state of event information
Position include be serial number 1 and 2 event information, followed by the event information if it is serial number 2 and 3, then show to deposit
Mistake is stored in event information, is directly entered S7；Followed by the serial number of event information be 1 and 2 respectively when, then show event
Information storage is correct, into next step；
After S6, event information collection are sent, host computer and electric energy meter disconnect communication connection；
S7, end.
The type of event information includes game clock lid, beginning lid, open upper cover, is reversed, line off zero, Qiang Ci, overload, over-voltage, owes
Pressure, decompression, negative phase sequence, clearing are latched, program, clock exception, RAM are random access memory exception, E2P exception i.e. electrically erasable extremely
Except memory exception, totally 16, a serial number is arranged in each type, for example, serial number 1 represents game clock lid, serial number 2 represents the beginning
Lid, and so on, the positive integer that the serial number of event information is arranged successively, maximum value M, M 16；The serial number of event information
It is stored with hexadecimal format, 16 event informations occupy 2 bytes, therefore the mode bit of event information is stored with hexadecimal
When need 2 bytes, 2 bytes include 16 bits, and 16 bits successively represent the serial number of 16 event informations, i.e., first
Bit is the event information of serial number 1, and the 16th bit is the event information of serial number 16, when a certain event information occurs
When, then by the bit position 1 where its serial number, when event information does not occur, bit corresponding to serial number is 0.Event letter
Date when occurring in breath including the serial number of the event information, the event information and Hour Minute Second those contents；Event information
The storage format of serial number of storage format and event information of content is consistent.
First event information, second event information ... nth event information are successively according to the successive of its time of origin
Sequence is arranged successively or first event information, second event information ... nth event information are successively big according to its serial number
It is small successively to arrange from small to large.
For example the time that the event information of serial number 1 occurs is 2018-12-01,18:30:01, the event letter of serial number 2
The time that breath occurs is 2018-12-01,18:30:03, the then storage format of the event information of serial number 1 are as follows: 0x01+0x18+
0x12+0x01+0x18+0x30+0x01；The storage format of the event information of serial number 2 are as follows: 0x02+0x18+0x12+0x01+
0x18+0x30+0x03；The then mode bit storage format of temporal information are as follows: 0x000x03, binary form mode are as follows:
0000000000000011, expression is meant, needs to read the content of the event information of serial number 1 and 2, then complete thing
The storage format of part information collection are as follows: 0x000x03+0x01+0x18+0x12+0x01+0x18+0x30+0x01+0x02+0x18+
0x12+0x01+0x18+0x30+0x03；This event information collection is sent to host computer perhaps host computer or system after system
Whole event informations can be disposably read, that is, the abnormal events information of game clock lid and beginning lid, host computer has occurred
Whole abnormal datas has been got, electric energy meter, therefore reading event of the present invention can accordingly be adjusted according to the abnormal data
The efficiency of information is higher, can greatly promote the managerial ability of host computer, while also can timely find the different of electric energy meter
Often.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that, it still can be to implementation above-mentioned
